When the electric impulse travels along the axon and reaches the other end called the synaptic terminal, this impulse triggers the release of – (1) Vesicles (2) Cleft (3) Mitochondria (4) All of the above

Description : When the electric impulse travels along the axon and reaches the other end called the synaptic terminal, this impulse triggers the release of – (1) Vesicles (2) Cleft (3) Mitochondria (4) All of the above
